Professional Applications & Engineering Value
This 1/4"-20 UNC fully threaded steel rod delivers critical engineering solutions where high tensile strength and corrosion resistance are paramount. Manufactured from ASTM Grade B7 steel, it maintains structural integrity under extreme temperatures and pressures commonly encountered in petrochemical, power generation, and heavy machinery applications. The coarse thread design provides superior vibration resistance compared to fine threads, while the Class 2A thread fit ensures consistent performance across multiple installations. The fully threaded configuration allows for adjustable positioning and maximum load distribution, solving common challenges in structural bracing, anchor systems, and machinery assembly where precise tension control is required.
Specification Summary & Compliance
This threaded rod maintains Class 2A thread fit tolerance with UNC coarse threading (1/4"-20) in right-hand direction. Manufacturing follows ASTM A193 specification for high-temperature service, with material certification to ASTM Grade B7 standards. The product demonstrates full compliance with RoHS 3 (2015/863/EU) restrictions and REACH (EC 1907/2006) regulations regarding substance control, ensuring environmental responsibility in industrial applications.
